Innokin really have thought this design through thoroughly. Excellent stuff.

How Does The Cool Fire 4 Perform?

I think we can gather that Innokin have nailed the looks and build quality but how about the performance.

Here are the specs of the MOD:

86mm height

2000 mAh Li-ion Battery

6W – 40W – Adjusted in 0.5W increments

3V – 7.5V – Adjusted in 0.1V increments

VRMS DC current

Output Current 12A

Max output current 14.5A

Tank resistance 0.3Ohm

Pass through (Vape While Charging)

510 Spring loaded pin

On/Off switch

15 Second Cut Off

Low volt warning

Overheat protection

Short circuit/Atomiser protection

Over discharge protection

Innokin have definitely packed in some features with the Cool Fire IV. I have been using the MOD now for a couple of weeks and the 2000 mAh battery has been getting me through a couple of days vaping before a charge is needed.

This is with the iSub with a 0.5ohm coil.

Depending on your setup this could last you less or indeed a lot more if you are just using the likes of the Aspire Nautilus Mini. So no issues on that front.

Selecting the various functions is very much a user friendly affair. The OLED screen is small but very clear and displays the following information:

Atomiser resistance

Voltage output

Wattage output

Battery power indicator

Pressing ‘Power’ button and ‘-‘ selects Watts

Pressing ‘Power’ button and ‘+’ selects Volts

Pressing both ‘+’ and ‘-‘ together shows number of puffs. Hold these for 3 seconds and the OLED screen flips.

And of course the ‘+’ ‘-‘ buttons scroll through the voltage/wattage settings

The functions all work seamlessly. The voltage/wattage selection display scrolls fast enough to get you to your desired setting quickly as well as using a ’round robin’ function so once it reached 40W it will go back to the beginning.

Go too far and you can of course go back the other way.

If, as a vaper, you are stepping up from an EGO e cig to a variable wattage device for the first time this really is simple to get the hang of.

As mentioned I was using the Innokin iSub tank, it looks the part paired with the Cool Fire 4 and the performance was excellent. All 22mm tanks actually fit perfectly on this MOD.

For new VW users just be sure to start your setting low and work your way up until you get to your preferred setting.

If you are just using sub ohm tanks the 40W range will be more than enough for your needs.

For those using RDA’s with lower resistance builds then it’s likely that 40W might not be enough depending on your build but if you fall into that bracket you already new that 🙂

Final Thoughts

Still recommended in 2017.. This mod has stood the test of time!

It takes a bit to get me excited about new box mods due to the fact a lot of brands don’t seem to create anything different, they just regurgitate what seems to be selling well and while they may create a good product you can’t help but just feel… Well…. merghhh.

Not so with the Innokin Cool Fire 4. This for me (along with the MVP3) is one of the best box mods to date for vapers that just use tanks and sub ohm tanks.

It really does look and feel fantastic.

Lets round it up:

Pro’s

Looks fantastic and feels fantastic in the hand. Top quality build.

Excellent 2000 mAh battery life

Simple to use

Clear OLED screen

Can be used as a pass through (Vape whilst charging)

Upto 40W which should be plenty for most vapers

510 and EGO compatible

Use coils down to 0.3Ohm

Portable, can easily be used out and about

Cons

The only tiny thing is the slight button rattle from the +/- buttons. And that’s being picky.

I've been vaping since 2010 and been cigarette free ever since. Ecigclick was started to take a closer look at the mixed bag of e cigs that were available at the time. We have gone from a handful of reviews in 2010 to now covering a huge range of vaping gear with over 100 reviews and counting today with the help of the great review team we have here!
I'm available on the blog most days, if you have any questions just use the contact tab and I'll get right back to you! Vape on...

Hi Johnny,
Thanks for the reply. Yes came with the iSub Tank. I’ll test out some other PG / VG mixes.
As I’m new to this, tried normal E-cigs to quit smoking, is it possible to use a mouth to lung setup with the Innokin Cool Fire 4 rather than straight to lung as it is at present. I think this may improve the experience overall.
Let me know your thoughts and any recommendations if this setup is possible. Great site by the way – the reason I bought an Innokin Cool Fire 4 – fantastic and honest reviews.
Cheers, Rob

Just bought one and received it today. Everything is great apart from the popping and crackling.
Does anyone know the correct settings – tried all the recommended and still getting the wake up noises.
Using a 100% PG mix – could that have something to do with it. Any recommendations very welcome.

Immediate thoughts, as you mentioned, is the 100%PG juice. You should get better results from a ratio around the 60VG/40PG range (if you have a sub ohm tank). 100PG is thin for these bigger coils and can soak through the cotton to the coils a little too quick.

Crackling and popping isn’t unusual but is a problem if your getting spit back. It’s juice sitting on the actual coil, when you fire the device the immediate temp increase can cause the eliquid to pop/crackle.

If it’s spitting a quick poke of rolled up tissue or Q tip down the mouthpiece into the center of the coil can mop up the excess. In fact, no harm in trying this anyway to clear some of the excess juice of the actual coil.

I have just purchased this product and it seems to be just what it says on the tin and works fine. The only thing I have noticed is that it uses a lot of fluids I am filling the tank twice a day which seems a lot. Has anyone else had this experience?

i own many(15+) box mods and to be honest if i have to go out all day i dont take this mod , but for an evening out , going shopping or any outing less than 6 hours , i always take this mod as it is small enough to put in my pocket , it feels great in my hand , easy to use , and it looks class .

The features are great, being little effort to operate. I love the size and battery life. Smooth hit every time. Gives a fulfilling sensation to negate the desire to use tobacco. I like the simple design, easy to read display. Ergonomic design and weight makes it such an easy pick up.

What can I say that hasn’t been said already? Superb ergonomic design, unmatched ease of use, and a beautiful looking mod. Flavour and vapour production is stellar. Can’t fault the Cool Fire IV at all, though if you’re looking for high wattages you might want to look at the Plus model.

Fantastic mod. This was my first venture into vaping, and it’s been a revelation for me. I never bought into the whole vaping thing until I tried this, now I wouldn’t use anything else.
I loved it so much, I’ve bought myself a second coolfore 4 so I’ve always got one in use and one charged and ready to go should the battery run out.
I’d recommend changing the tank to an ISub S. It’s a top filler and saves having to dismantle the tank when needing a refill.
Overall I couldn’t recommend this enough, don’t think about it, get one, change the tank and I guarantee you won’t be disappointed

Before I got this ecig I was smoking 10-15 fags a day at I seemed to smoke more at work but since iv got this ecig iv not bought any fags since iv not smoked any fags since tbh I don’t eaven think about having a fag no more the ecig is enough to make you feel like you have had a fag it’s a really good thing to have when ever I feel like I want a fag I have a couple of puffs on ecig thn I don’t eaven think about it anymore

I bought this as a friend of mine had one, i have smoked for 40yrs, i cannot believe that i have given up smoking so far whilst using the cool fire.
My cool fire 4 came with a isub tank, i did not like that tank as it was like sucking on a exhaust pipe, so i chaned to a iclear 30 now i’m a happy bunny..
